St. Spiridon was a Bishop of Tremithus on Cyprus. He had been tortured during the Galerian persecution, but adhered to Christianity. He is known to have attended the council of Nicaea in 325 AD. He died in 348. As he had worked numerous miracles and his body did not decay after death, he was declared a saint. When Cyprus was threatened by Turkish invasion, his body was removed to Constantinople and in 1453, shortly before the fall of the city, to Corfu.

He became Corfu's patron saint, and his body is located in St. Spiridon in Corfu-city. The sandals of his relics have to be replaced every year, therefore he is known as the walking saint.

There is a procession with the Saint's relics every year on 11 August to commemorate the lifting of the Osmanic siege in 1716.
